ln operation my machine is adapted to be supported upon a suitable trestle or scaiold i which may consist of any lightstructure readily assembled and demolished and upon which temporary rails 2 are secured upon which the traction wheels 3 of my machine travel. Midway between the rails 2 a cog track 4 is secured upon 'which the cog 5 mounted upon the axle 6 of the traction Whoo@I travels to propel the machine from place -o place. The axle 6 is rotated by a pulley mounted thereupon that is beltconnected as at 7 to a suitable transmission mounted upon a shaft 8 that is gear-connected to and operable by the main motor 9 that. is disposed upon the base or floor 10 of the machine. Upon the Hoor 10 are corner posts 11, four in number, additionally supported bybraces 12 that join them with the base, and the said corner posts in connection with the base form the skeletonV or real frame of my machine. To each corner post l1 a rack 13 is secured upon which wheels 14 travel that support the parts oi" my machine that are independent of the main frame just described. r1`he shafts 15 of these wheels which extend from side to sidevof the complete machine are secured to the hopper 1G and support the same and the three wheels 141 on either side of the machine are operated y a chain 17 engaging ratchets 17a keyed to shafts 15 so that power maybe transmitted from one of the sha-tts 15 which at d its termination is formed square in cross section as shown in Fig. 1 to permit. engagement therewith by a crank by which it is rotated to'cause the wheels 14 to travel vertically over the racks 13 thus raising or lowering the hopper and the mechanism con'- nected thereto; the traveling portion just ldescribed may be locked in any desired position through the medium ot' a. pawl 18 sccured to a traveling floor 19 that is secured by supports 20 to the hopper 16. lNithin the hopper 16 istil partition 21 that divides the same into two compartments, the forward compartment being used for brick and the rear compartment for mortarl Near the| lower end 'of the front wall of the forward or brick compartmentof the hopper a trap door 22 is pivotally carried as at 23 which when in closed position serves as a floor for the same to keep the 'bricks within the hopper and when open serves as outlet for the said bricks one at a time. The movements of the trap door are regulated by a liti cam which is formed with a V-shaped peripheral indenture and with a plurality of irregular shoulders over the balance ot its periphery. 'lhe irregular periphery ot' the cam, which cani is constant-ly in contact with the trap door, is to oscillate the said door and so keep the bricks within the hopper in a state of agitation which will tend to position them so that when the V-shaped indentation permits the downward thrust of the door but one brick may rind an outlet from the hopper and ride around with the cam,

which is disposed upon a shaft 25 journaled in the hopper' and receiving power from a wheel ZG connected with a transmission chain 27 to the drive wheel ot the motor, to the lower termination of the partition 21 in the hopper.

28 is a trough secured to the front wall of the hopper and provided with a pair of lateral L-shaped runways 29 extending loir gitudinally almost from one end to the other. lhe side walls of the said trough are slotted as at 30 to receive transverse shafts 31 that are movable longitudinally of the said trough and that are each provided with a (log-32. The said dogs extend alternately in an up and a down direction from their shafts and are made fast thereupon. The lateral walls of the said trough are further provided with longitudinally extending eX- terior guides 33 between which movable slides 35 are arranged which carry the shafts 31 and in which one end of a coil spring 3G vis secured the body of which is Wound upon the said shafts 31, to permit oscilla' tion of the said shafts in one direction but to prevent it in the opposite direction. To the front and rear ends of the trough 28 depending supports 37 are secured that carry a, track 38 in which the wheels 39 ot' a truck 40 travel; the forward 'end of the truck i0 terminates in a head 11 which is projected upward almost into alinement with the runways 29 that carry the brick and the head 41 is provided with a transverse shaft 42 that carries a dog l13. lt will be noticed that the dogs 32 are spaced apart a distance slightly in excess Aof the length of a brick. The bricks are loaded upon the runways 29 by the cam 94 as previously described, each succeeding brick `forcing its predecessor forward one brick-length as the cam rotates until the runways are full. At this point crank arms 144 are connected to one of the shafts 31 and to cranks l5 in their slot-ted portions /l-G which cranks are tcrininally secured to a. crank shaft 17 that retained by brackets 4S secured to a 'upport 49 that is connected to the hopper. Upon the shaft 47 is a cog 50 that is chainconncctcd to a cog 51 mounted upon a shaft E7 which shaft receives power from the motor. When the runways Q9 are illcd with bricks the power is applied and the shatt 21.7

" Lili? given one complete revolution which operation ad\;ances the dogs 32 and their connec- .y tions forward approximately one brick length and causes the remote terminal dog' to thrust one brick Yover theI dog` 43 into the angular head 11 of the trilck 10, this arrangement forming practically a conveyor. l n the modification Fig. 9 converging ridges B disposed upon the runways 29 cause the bricks to turn upon their sides as they advance and to Abe so deposited upon the wall vanced in the manner just described. At the end of the rear wall of the hopper an inclined pivoted Uate 55 is secured and the same is adjusta le through pin-connection with a rod 56 and the mortar passing over this gate is forced into the angular head 4l where it is ready for the bricks as they are singly deposited. With the mortared brick in the angular head the truck 40 is now advanced to the wall by means of a pitman 57 secured to the said truck and toa rack' 58. This rack is supported between two wheels 59 and 60 which are carried, respectively, l

terminally by arms 61 and 62; the opposite end of the arm G2 being pivot-ed to a bracket G3 secured to the support 2O and the oppo* site end of the arm 61 is pivotcd to the traveling licor 19. Bell crank levers 64 are pivoted between their extremities to the Hoor 19 and one termination of each of which is slotted and is pin-connected as at G5 to the cross-arms G1, 62. Rods G6, 67 connectthe bell crank levers 64 with a lever 68 which is used to depress the forward end of the rack 58 into mesh with a rotary cog 69 carried by a standard 70 disposed upon the traveling door 19; or the said lever when moved in the opposite direction will raisd the front end of the said rack throwing its lower serrated surface into contact with the cog G9 and reversing the movement of the said rack and its connections thus actuating the truck 40 with the said rack. l'Vhen the .mechanism is used to advance the truck 40 to the wall 71 the brick carried by the head 41 is placed in position upon the said wall i as shown in Fig. 1.

To one of the corner postsll of the main vframe a socket 72 is secured which retains a sliding rod 73 that terminally supports a plumb i5 to keep the building wall in proper alincmcnt. To the shaft of the said plumb an upright spirit le'vel 75 and a hori zontal spirit level 76 are secured for use upon the wall. f

77 is a lug secured to the shaft ot the plumb that carries a pirotcd guide arm 78 iu which is carried au arm .T9 between two set screws 80. This arm is adapted to enter between the brick on the head atl and the dog 43 to hold the brick in its position upon the Wall when the truck 40 is drawn back to its normal position.

81 is a bracket secured to one Wall of the trough Q8 and provided with two shafts 8l', S2 upon which hammers 33, 8i made integral, respectively, with curved arms S5, SG are disposed. One hammer 83 is formed with an oii'set to permit passage of the. other hammer when in operation as shown in Fig. 13. A bracket 87 is fitted over the juncture of the hammer 83 with its arm 85 and a. similar bracket over the juncture of the hammer 8a with its arm 86 and both are disposed upon the shafts Sl or 82, While springs 88, 8S connect the upper end of either bracket 87 With the arm 85 or the arm 8G.

S9 is a cam mounted upon a sha-ft 90 carried by the bracket 8l and Whenthis shaft is rotated by handle 9() the said cam intere mittently engages the adjacent free ends of" the arms S5, S6 depressing them and so depressing'the hammers and causing them to strike sharp blows upon the brick directly beneath them.

91 is the operat-ors platform secured to the traveling ioor 19.

92 is an auxiliary motor disposed upon the floor 1S) and designed to supply power 'for the traveling mechanism when it is desired to vary the position of the traveling parts.
